=head1 NAME
Apache::lonmenu
=head1 SYNOPSIS
Loads contents of /home/httpd/lonTabs/mydesk.tab,
used to generate inline menu, and Main Menu page.
This is part of the LearningOnline Network with CAPA project
described at http://www.lon-capa.org.
=head1 GLOBAL VARIABLES
=over
=item @desklines
Each element of this array contains a line of mydesk.tab that doesn't start with
cat, prim or scnd.
It gets filled in the BEGIN block of this module.
=item %category_names
The keys of this hash are the abbreviations used in mydesk.tab in those lines that
start with cat, the values are strings representing titles.
It gets filled in the BEGIN block of this module.
=item %category_members
TODO
=item %category_positions
The keys of this hash are the abbreviations used in mydesk.tab in those lines that
start with cat, its values are position vectors (column, row).
It gets filled in the BEGIN block of this module.
=item $readdesk
Indicates that mydesk.tab has been read.
It is set to 'done' in the BEGIN block of this module.
=item @primary_menu
The elements of this array reference arrays that are made up of the components
of those lines of mydesk.tab that start with prim:.
It is used by primary_menu() to generate the corresponding menu.
It gets filled in the BEGIN block of this module.
=item %primary_sub_menu
The keys of this hash reference are the names of items in the primary_menu array
which have sub-menus. For each key, the corresponding value is a reference to
an array containing components extracted from lines in mydesk.tab which begin
with primsub:.
This hash, which is used by primary_menu to generate sub-menus, is populated in
the BEGIN block.
=item @secondary_menu
The elements of this array reference arrays that are made up of the components
of those lines of mydesk.tab that start with scnd.
It is used by secondary_menu() to generate the corresponding menu.
It gets filled in the BEGIN block of this module.
=back
=head1 SUBROUTINES
=over
=item prep_menuitems(\@menuitem)
This routine wraps a menuitem in proper HTML. It is used by primary_menu() and
secondary_menu().
=item primary_menu()
This routine evaluates @primary_menu and returns a two item array,
with the array elements containing XHTML for the left and right sides of
the menu that contains the following links: About, Message, Roles, Help, Logout
@primary_menu is filled within the BEGIN block of this module with
entries from mydesk.tab
=item secondary_menu()
Same as primary_menu() but operates on @secondary_menu.
=item create_submenu()
Creates XHTML for unordered list of sub-menu items which belong to a
particular top-level menu item. Uses hover pseudo class in css to display
dropdown list when mouse hovers over top-level item. Support for IE6
(no hover psuedo class) via LC_hoverable class for <li> tag for top-
level item, which employs jQuery to handle behavior on mouseover.
Inputs: 4 - (a) link and (b) target for anchor href in top level item,
(c) title for text wrapped by anchor tag in top level item.
(d) reference to array of arrays of sub-menu items.
The underlying datastructure used in (d) contains data from mydesk.tab.
It consists of an array which has an array for each item appearing in
the menu (e.g. [["link", "title", "condition"]] for a single-item menu).
create_submenu() supports also the creation of XHTML for nested dropdown
menus represented by unordered lists. This is done by replacing the
scalar used for the link with an arrayreference containing the menuitems
for the nested menu. This can be done recursively so that the next menu
may also contain nested submenus.
Example:
[ # begin of datastructure
["/home/", "Home", "condition1"], # 1st item of the 1st layer menu
[ # 2nd item of the 1st layer menu
[ # anon. array for nested menu
["/path1", "Path1", undef], # 1st item of the 2nd layer menu
["/path2", "Path2", undef], # 2nd item of the 2nd layer menu
[ # 3rd item of the 2nd layer menu
[[...], [...], ..., [...]], # containing another menu layer
"Sub-Sub-Menu", # title for this container
undef
]
], # end of array/nested menu
"Sub-Menu", # title for the container item
undef
] # end of 2nd item of the 1st layer menu
]
=item innerregister()
This gets called in order to register a URL in the body of the document
=item clear()
=item switch()
Switch a button or create a link
Switch acts on the javascript that is executed when a button is clicked.
The javascript is usually similar to "go('/adm/roles')" or "cstrgo(..)".
=item secondlevel()
=item openmenu()
=item inlinemenu()
=item rawconfig()
=item utilityfunctions()
Output from this routine is a number of javascript functions called by
items in the inline menu, and in some cases items in the Main Menu page.
=item serverform()
=item constspaceform()
=item get_nav_status()
=item hidden_button_check()
=item roles_selector()
=item jump_to_role()
